South West England is one of the regions of England defined by the Government of the United Kingdom for statistical and other purposes. It is the largest such region in area, covering 9,200 square miles (23,828 km²) and comprising Bristol, Gloucestershire, Somerset, Dorset, Wiltshire, Devon, Cornwall and the Isles of Scilly. Five million people live there. The region includes the area often known as the West Country, and much of Wessex. The size of the region is shown by the fact that the northern part of Gloucestershire, near Chipping Campden, is as close to the Scottish border as it is to the tip of Cornwall. The largest city is Bristol. Other major urban centres include Plymouth, Swindon, Gloucester, Exeter, Bath, and the South East Dorset conurbation of Bournemouth, Poole and Christchurch.

The region includes two National Parks and four World Heritage Sites, including Stonehenge.

Traditionally, the South West of England has been well known for producing Cheddar cheese, which originated in the Somerset village of Cheddar, for Devon cream teas, Cornish pasties, and for cider. It is also well known as the home of the Eden Project, Aardman Animations, the Glastonbury Festival, the Bristol International Balloon Fiesta, trip hop music and also Cornwall's surfing beaches.

England ⁱ/ˈɪŋɡlənd/ is a country that is part of the United Kingdom. It shares land borders with Scotland to the north and Wales to the west; the Irish Sea is to the north west, the Celtic Sea to the south west, while the North Sea to the east and the English Channel to the south separate it from continental Europe. Most of England comprises the central and southern part of the island of Great Britain in the North Atlantic. The country also includes over 100 smaller islands such as the Isles of Scilly and the Isle of Wight.

The area now called England was first inhabited by modern humans during the Upper Palaeolithic period, but it takes its name from the Angles, one of the Germanic tribes who settled during the 5th and 6th centuries. England became a unified state in AD 927, and since the Age of Discovery, which began during the 15th century, has had a significant cultural and legal impact on the wider world. The English language, the Anglican Church, and English law—the basis for the common law legal systems of many other countries around the world—developed in England, and the country's parliamentary system of government has been widely adopted by other nations. The Industrial Revolution began in 18th-century England, transforming its society into the world's first industrialised nation. England's Royal Society laid the foundations of modern experimental science.
